I think you fellows are taking these terms far too seriously.  There is nothing scientific about this.  A day that is "kind of cold" is not 6.7 degrees colder than a day that is "sort of cold", and a woman who is "pretty honest" is not 2.6 more likely to steal from you than a woman who more "somewhat honest".  What is the context?  What is the intent of the speaker?  It's a bit like asking when a girl stops being pretty and become beautiful, when a breeze changes from cold to cool, from warm to hot, a meal from great to fantastic.  It's all a matter of personal opinion.

very good......wait a moment....awesome explanation :)
